RAIL-JOINT.

Specification of Letters Patent.

Patented Juiie 27, 1916'.

Application filed October 13,1915. Serial No. 55,699.

Be it known that I, HENRY EMERY Comimic, a subject of Great Britain,residing at West Milan, in the county of Coos and State of NewHampshire, have invented new and useful Improvements in Rail- Joints, ofwhich the following is a specification.

The invention relates to improvements in rail joints, and has specialreference to means for facilitating the application of rail joints inlaying rails.

To this end the invention has primarily in view a simple, novel andpractical expedient which will enable trackmen to apply rail joints torails with facility and accuracy, and in a like manner to permit of theseparation of the members comprising the joint should either of therails or any of the members of the joint become worn and therebysupplanted by a new part therefor.

Another object of the invention is to construct the rails withinterengaging ends; to provide a rib member for engaging a groove in thebase of said rails and to further 'provide a sleeve which is adapted tobe moved longitudinally over the base portion of the rails to envelopthe rib member and lock the interengaging ends of the rails to hold thesaid rails in positive alinement.

A further obje'ct'of the invention is to construct a rail having its webenlarged at its end and sheared or stamped to provide verticallydisposed lapping sides, the ends of which being received in depressionsprovided above the base of the rail on said sheared or stamped portionsthereof, and further to provide the rail ends with a thickened basewhich extends below the base proper, to form the said thickened portionwith a longitudinally extending groove, to

receive the rib of the rib member, the ends provided by the channel ofthe said me'mber contacting wit'h the inner ends of the thickenedportions of the base of the rail, to provide a slidable sleeve upon oneof the rails ada ted to be moved over-the member provided with the ribwell as to engage with the upper horizontally straight base" portion ofthe rail in positive engagement.

Removable means are provided for retainng the sleeve in locked positionsupon the oint, and thus produce a joint which will retain the railsagainst lateral or vertical movement and to permit only a limitedlongitudinal movement incident to the expansion and contraction or therails and to further render the rails at the oint thereof of a strengthas great, if not greater, than at any other portion of the rails.

A stillfurther objectof the invention to produce a rail joint which willembody the desirable features of 'che'apness, simplicity, durability andeflic'iency.

The essential features of the device in volved in the provision of arailjoint arenecessarily susceptible of a range of structural modificationswithout departing from the scope of the invention, but desirableillustrative embodiments of the latter are shown -in the accompanyingdrawings, in which: V

parts being broken way, and parts being shown In section, Flg. 5 1s adetail transverse section approximately on the line 5-5 of y Fig. 4:,Fig. 6 is a perspective View of one-of th rail ends, Fig. 7 is a similarview of the ribbed base member or block, and Fig. 8 is a similar View ofthe locking sleeve;

In carrying out my invention, the rails I the rails, at'th'e saidhorizontally straight portions 2 being thickened upon theirunderfaces toprovide, substantially re'ctangu-. lar depending members 3, and thesemeta bers, from the outer and straight walls 4 thereof and upon theirunderfaces are formed with a centrally arranged groove 5, the upper wallof which being arranged in a line flush with the underfaces of the baseof the rail. The head of each of the rails, at the thickened webthereof, which, for dis tinction, is indicated by the numeral 6, issheared or stamped to provide an extension 7, the inner vertical wall 8of which being arranged centrally and longitudinally of the rail andterminating in a transverse shoulder 9. The extension 7 projects adistance beyond the end wall t equal to the distance between the saidend wall and the shoulder 9. The depending or widened portions 3 of thebase are only slight, approximately onehalf of an inch, and the lengthsof the said members 3 are approximately two inches in length, so that itwill be noted that the extension 7 provides a tongue which is also of acomparatively short length, and as the question of dimensions becomes amatter of prime importance in the process of manufacture, the forging orstamping of the rail. ends, which, it will be noted are of a similarconstruction at both the ends of the rails, can be made from the samedie or machine, so that precision, rapidity and economy in stamping therail ends will be assured.

-This is, of course, of practical importance both from a manufacturingstandpoint and from an engineering standpoint. It will be further notedthat except for the tongue 8 no other projections are provided upon therail ends which might interfere with the free removal of the rail shouldit be found necessary to remove either of the rails, and When the rails.are assembled the projections or tongues 8 lap.

The oint includes a base member or block 10 which has itsupper facechanneled transversely to provide. a horizontally straight portion 11and vertical shoulders 12 which provide the end walls of said straightportion 11. The block is also centrally formed with a longitudinallyextending rib 13 which connects the shoulders 12, and the said blockadjacent one of its ends and adjacent its lower face is formed with atransverse head or flange 14. The distance between the shoulders 12 isslightly in excess of the combined width of the depending portions 3 ofthe base of the rails and the block is applied by simply slipping thesame over the rails to bring its rib 13 within the grooves 5, theshoulders 12 being disposed adjacent the vertical end walls 15 provided.by the depending portions 3. However, be-

fore the block 10 is thus positioned the slidable sleeve 16 is arrangedupon one of the rails and moved a distance away from the end of the saidrail. This sleeve comprises a substantially rectangular hollow member ofan interior width approximately equaling the width of the block 10 whichcorresponds with the width of the base flanges of the rails and ofcourse the width of the depending portions 3 at the ends of said ribs.The interior height of the sleeve equals the distance between the lowerface of the block 10 and the horizontally straight surface 2 providedupon the rail ends. The top member 17 of the sleeve is cut centrally andlongitudinally forming the same with an opening 18, the width of whichbeing equal to the width of the thickened ends of the rails. After theblock has been positioned, as previously stated, the sleeve is forcedlongitudinally over the horizontally straight portions 2 of the railends and underface of the block until. one of the ends of the sleevecontacts with the flange or bead 14-. The inner surfaces of the sleeveengage with the block, the sides of the vertically straight dependingportions 3 of the ends and the upper horizontal surface 2 of the baseflanges of the rails, as well as with the sides of the widened portions6 and the outer surface of the tongues or extensions 7 with siuiicientfriction to normally prevent the accidental removal of the sleeve fromthe joint, but in order to positively lock the said sleeve upon thejoint, the widened end of the block 10 opposite that provided with thebead 1 1 is formed with a transverse opening 19 through which is passeda securing element 20, the same being preferably in the nature of acotter pin and has its ends bent in opposite directions, so that thehead thereof as well as the said bent ends will contact with one of theends of the sleeve and thus effectively hold the sleeve in lockedposition.

A rail joint constructed as above described, has the advantages ofsimplicity and strength which will be apparent to those skilled in theart to which such inven tion appertains and while other embodiments maypresent themselves to those familiar with the art, it is believed thatthe device as herein described will exemplify the uses and advantages ofthe improvements claimed.

Having thus described the invention, what I claim is:

1. In a rail joint, two rails having lapping ends each resting upon thebase of the other rail, a block having a rib which is arranged in agroove in the underface of the base flanges of the rail, and a slidablesleeve contacting with the rail ends enveloping the block. 7

In a rail joint, two rails having reduced head and web extensionswhich are adapted to lap and one to rest upon the base of the other,said rails having their underfaces provided with alining grooves, anumber having a rib which is received in the grooves, and a slidablesleeve contacting with the rail ends and the extensions thereof engagingwith the rib member and sustaining the rib in the grooves.

3. In a rail joint, two rails having reduced head and web extensionswhich are adapted to lap and one to rest upon the base of the other,said rails having their underfaces provided with alining grooves, amember having a rib which is received in the grooves, and a slidablesleeve contacting with the rail ends and the extensions thereof engagingwith the ribbed member, and means for locking the sleeve in suchposition.

4. In a rail oint, two rails having reduced head and web extensionswhich are adapted to lap and one to rest upon the base of the other,said rails having their underfaces provi ded with alining grooves, amember having a rib and said rib received in the grooves, and a slidablesleeve contacting with the rail ends and the extensions thereof engagingwith the ribbed member, and removable means for locking the sleeve insuch position.

5. In a rail joint, two railshaving their webs widened at the endsthereof, their base flanges elevated to provide horizontal portions,thickened below the said horizontal portions, the said thickenedportions being centrally formed with a groove. the head of the railextending beyond the thickened base and being sheared'or stamped toprovide a lateral tongue and a transverse shoulder which is disposedover the horizontal portion of the base and the said extensions adaptedto lap and have their ends contact with the shoulders and rest on thehorizontal upper face of the base to bring their grooves in register, ablock having a depressed upper face providing a central longitudinal ribadapted to be received in the grooves and having the end walls providedby the depressions disposed adjacent the inner ends of the dependingportions ofthe base, and a longitudinally movable sleeve arranged uponthe flanges elevated to provide horizontal portions, thickened below thesaid horizontal portions, the said thickened portions being centrallyformed with a groove, the head of each rail extending beyond thethickened base and being sheared or stamped to provide a lateral tongueand a transverse shoulder which is disposed over the horizontal portionof the base, and the said extensions adapted to lap and have their endscontacting with the shoulders and rest on the horizontal upper face ofthe base to bring their grooves in register, a block having its upperface depressed and centrally formed with a longitudinal rib which isadapted to be received in the grooves of the rails, said block havingits underface adjacent one of its ends provided with a stop bead and itsopposite end provided with a transverse opening, a substantiallyrectangular sleeve arranged upon one of the rails, said sleeve havingits upper face provided with a central longitudinal opening of a widthapproximately equaling the width of the widened ends of the said rails,said sleeve adapted to be moved longitudinally over the rail ends andthe block to contact with the stop head of the block, and a lockingelement passing through the opening in the block and contacting with oneof the ends of the sleeve.
